Parse enclosure tag from rss feed

I am pulling in a rss feed with this script and parsing the standard tags like so...

<?php
error_reporting(E_ALL);

$xml = file_get_contents('http://feedurlhere');

// MUNG THE XML BECAUSE WE DO NOT HAVE THE NAMESPACE INFORMATION
$xml = str_replace('content:encoded', 'content__encoded', $xml);
$xml = str_replace('isc:',            'isc__',            $xml);

// CONVERT THE XML TO AN OBJECT
$obj = SimpleXML_Load_String($xml, 'SimpleXMLElement', LIBXML_NOCDATA);


// GET SOME FIELDS
$item_title = $obj->channel->item->title;
$item_link = $obj->channel->item->link;
$item_description = $obj->channel->item->description;

echo "$item_image<br/><strong>$item_title</strong> $item_description<br/>";

?>

Here is my problem... I want to grab the url within this enclosure tag and I am not sure how... $obj->channel->item->enclosure does not get me there.

<enclosure url="http://domain.com/blog/wp-content/uploads/2011/08/Arms21-150x150.jpg" length="6060" type="image/jpg" />

A feed with a name like feedurlhere or a URL with a name like domain.com is almost completely useless.  Please post the actual URL of the feed so we can see the actual contents of the XML statements in the feed.  Then we can show you how to parse the feed and extract the URL.  It is not the same for every feed, and we need to be able to read the XML in order to answer you correctly. Thanks, ~Ray

If you want the url as an "object" use:
$attrib= $obj->channel->item->enclosure->attributes()->url

If you just want the "string" value, then use:
echo (string)$obj->channel->item->enclosure->attributes()->url

Got it working with this...   $item_image = $item->enclosure->attributes()->url;
